These are high quality strings with no mechanical problems. They stay in tune, feel good under the hand, and intonate properly. They also seem quite durable - I have been playing my set regularly for a month and they show virtually no wear.

On the other hand, the treble strings have an extremely glassy, metallic sound that can become shrill and artificial sounding. They are not suited to my cedar-top guitar at all, and I cannot imagine that many classical guitarists would find their tone attractive. These might be more appropriate for another musical style. The bass strings sound fine.

These strings are perfect for ANY style of nylon playing. They feel soft and they sound soft, but use a pick and they are brighter than D'Addario's, these things will last forever too, and after a week or two , they never go out of tune. BUY THESE STRINGS!!! can't go wrong
